Lawmakers bashed Donald Trump Jr. Tuesday, calling for the real estate scion to testify about his meeting with a Russian lawyer who allegedly promised intel on the Clinton campaign.

Trump Jr. earlier in the day tweeted an email exchange from 2016 in which he agreed to meet with a "Russian government" lawyer with dirt on Hillary Clinton as "part of Russia and its government's support for Mr. Trump."

"Anytime you're in a campaign and you get an offer from a foreign government to help your campaign, the answer is no," Graham (photo) told reporters Tuesday. "So I don't know what Mr. Trump Jr.'s version of the facts are. Definitely — he has to testify."

The ranking Democrat on the Senate Intelligence Committee said the emails showed Trump associates repeatedly lied about their ties to Russia.

"All of these denials that we have heard in the campaign, during the transition, in the administration that there were no contacts with Russians, no discussions about the campaign are all patently false," the Virginia senator said. "It means we have a lot more questions to ask of Trump campaign officials."

Senate Intelligence Chairman Richard Burr (R-N.C.) said he's seen the emails, but declined to weigh in on their contents.

"New emails from @DonaldJTrumpJr contradict a lot of prior story from yesterday and before. This is not the same thing," the Long Island Republican tweeted. "I voted for @POTUS last Nov. & want him & USA to succeed, but that meeting, given that email chain just released, is a big no-no."

Some Republicans just shrugged off the revelations, noting that Trump Jr. doesn't hold a post in the White House.

"I don't think that's relevant to the Trump administration," Sen. Orrin Hatch (R-Utah) said of the emails, even though Trump's senior adviser, son-in-law Jared Kushner, was on the email chain and attended the meeting.

Conservative activist Charlie Kirk tweeted in defense of Trump Jr. — seeing his release of the emails minutes ahead of a New York Times story on them as a win.

"Don JR beats the fake news to the punch and releases the entire email chain. Nothing here is even borderline. This is just basic campaigning," he wrote.
